Synthetic Materials: this New-designed mini energy amplifier is product of noble black immersion gold circuit board, imported KEMET speaker capacitor, large-capacity filter capacitor for channels. Apart from, we custom-made black copper terminal blocks and gold-plated audio enter terminal blocks for this new amplifier module.
Excessive Efficiency: the digital amplifier module is with excessive effectivity of over 90%, common harmonic distortion noise is lower than 10%, low quiescent present and noise suppression.
Protected Safety: the category D dual-channel amp board is designed with enter reverse connection safety, brief circuit safety, over warmth safety; what’s extra, EMI is allowed to cross.
Extra Operate: it’s out there to attach amplifier sort to decide on completely different perform (MODE: excessive electrical energy stage is Kind D, low electrical energy stage is Kind AB. Manufacturing unit defaults excessive electrical energy stage); out there so as to add an exterior Shutdown (SD: the chip might be Shutdown at low electrical energy stage, manufacturing facility default excessive electrical energy stage.
